Troponin T

Q: What is the normal range for Troponin T?

The standard teaching reference range for Troponin T is < 0.01 (assay-dependent) ng/mL in conventional units, or < 0.01 µg/L in SI units. This value is measured in serum or plasma. Reference ranges vary by laboratory, method, age, sex, and population - always use the range printed on the actual result.

Q: What causes a high Troponin T?

Common causes of a high Troponin T: Acute MI; Myocarditis; Sepsis or critical illness; Chronic kidney disease.

Q: What injury threshold is taught for Troponin T?

For Troponin T, the commonly taught injury threshold is: Elevation above the assay's 99th percentile indicates myocardial injury.

Normal range < 0.01 (assay-dependent) ng/mL (< 0.01 µg/L SI). Specimen: Serum or plasma.

Also known as: cTnT, cardiac troponin T.

Reference range

This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.

Combined adult band. LabVals does not publish separate men's, women's, or pediatric ranges for Troponin T; those can be narrower than the band shown.
